MILL.

To all whom it may concern.

Be it known that we, Isiiiari C. LANnns and MIL'roN C. LANDES, both citizens of the United States, and resident of Yerkes, in the county of Montgomery and State of Pennsylvania, have invented a new and Improved Mill, of which the following .is a full, clear, and exact description.

Uur invention relates to mills, and more particularly to mills for grinding middlings, and it has for its object to provide one in which the material entering the mill is caught by an auger having openings, the material being caught by the blade on the auger, and being forced by the auger into a recess formed by a disk and the casing of the mill, where the rotation of the material is retarded by radial stops, while the blades of the auger act on the middlings to break it up, so that it may be bolted through bolting cloth. The material discharges between the periphery of the disk and the ring, and as the disk may be moved to or from the ring, the size of the discharge openings may be adjusted to retard the discharge of the middlings as desired, thereby maintaining the middlings in the recess a predetermined time to regulate the grinding. Adjustable means are provided for holding the disk yieldingly in the direction of the auger, to regulate the movement autoi'natically, so that it may accommodate the middlings should the middlings be fed into the mill in an unusually large quantity at any time.

Additional objects of our invention will appear in the following complete specification, in which the preferred form of our invention is disclosed.

In the drawings, similar characters of ref erence indicate corresponding parts in all the views, in which Figure 1 is a sectional elevation of the mill; Fig. 2 is an elevation of the auger, showing the casing around the auger in section; Fig. 3 is a side elevation of the auger; Fig. 4 is an elevation of the ring with the radial stops; Fig. 5 is a sectional elevation of Fig. 4; Fig. 6 is an elevation showing the disk; and Fig. 7 is a side elevation of the disk shown in Fig. 6.

By referring to the drawings, it will be seen that a frame 5 is provided, having a feed hopper 6, and an opening 7 in which a bearing 8 is mounted, in which is j ournaled Specification of Letters Patent.

the shaft 9, this shaft 9 being also ournaled in a bearing 10, secured in an opening 11 in the frame This bearing has a flange 12, against which presses a steel ring 13, which is engaged by the balls 14 which are pressed against the steel ring 13 by the steel plate 15, this steel plate 15 being engaged by the hub 16 of the pulley 17, the pulley 17 being secured to the shaft 9. The shaft 9 is driven by a pulley 1S, and the said shaft 9 is connected with a shaft 19 by means of the belt 20, which connects the pulley 17 with the pulley 21 mounted on the said shaft 19. This shaft 19 is journaled in a bearing 22 supported on the frame 5. To the shaft 9 is secured the auger 23, the auger 23 having four peripheral spiral members 24, the free terminals 25 of which have radially-disposed teeth 26. These spiral members 24 are mounted on the arms 27 of the auger, the rear 28 of these arms 27 being formed into blades for drawing the middlings through the auger when the anger is rotated. The middlings, after passing through the auger, being operated on by the radial teeth 26 on the terminals 25 of the spiral members.

As shown in Figs. 1 and 2 of the drawings, the hopper 6 is continued to form a cylindrical casing 29, in which the auger rotates. In an opening 30 in the frame, there is secured a bearing 31, in which is journaled the shaft 32, a disk member 33 being secured to this shaft 32. This disk member 33 has a cylindrical portion 34, which is disposed within the spiral members 24 of the auger 23, and the said disk member has a conical surface 35 leading to its said cylindrical portion 34. Secured between the casing 29 and a member 36 which con nects the said casing 29 with the casing 37, forming the discharge 38, there is a ring 39, having radially disposed teeth 40, the surfaces 41 of the said teeth being disposed substantially parallel with the cone-shaped surface 35 of the disk 33, when the said cone shaped surface is disposed in close proximity to the teeth 40. The other surfaces 42 of these teeth 40 are disposed at right-angles to the axis of the shaft 32.

The shaft 19 is not only journaled in a, bearing 22, but it is also journaled in a hearing 43, and to this shaft there is secured a gear wheel 44, which meshes with a gear wheel 45 secured to the shaft 32. It will therefore be seen that the shaft 32 will rotate in a direction opposite to the direction of rotation of the shaft 9. In an opening 46 in a member 47 mounted on the frame, there is a bearing 48, in which the end 49 of the shaft 32 is ournaled, the end 49 of the shaft being engaged by a thrust bearing 50, which is adapted to slide in the bearing l8, and which has a finger 51, adapted to be engaged by a lever 52, the said lever being fulcrumed at 53 to the frame, and having a bent arm 54, on which a weight 55 is disposed. It will be understood that this weight 55 tends to hold the arm 54 downward, which causes the lever 52 to press against the finger 51 of the thrust bearing 50, to push the thrust bearing 50 inwardly, and with it the shaft 52, so thatit will move the disk member 33 in the direction of the shaft 9. To the'finger 51 there is secured a disk 56, having a projection 57, which is engaged by the lever 52, preventing the finger 51 from rotating to free the parts of the thrust bearing 50. Then the mill is operated, the shaft 9 is rotated by the pulley 18, and the middlings are fed into the mill at the hopper o.

The middlings are engaged by the blades 28 on the arms 27 of the auger 23, which force the middlings through the auger, where they are held against rotation by the radial teethO, so that the middlings will 7 be acted on by the radially disposed teeth 26. The middlings then pass between the radially-disposed teeth 40, to the conicallyshaped portion 35 of the disk member 33, the middlings passing to the discharge 38, between the outer periphery of the conically-shaped portion 35 of the disk member 33 and the ring 39. The inner periphery of the ring 39 is disposed inwardly in the direction of the discharge to lead the middlings to the discharge opening between the ring 39 and the periphery of the conically-shaped member 35 of the disk 33. As has been stated, this disk member 33 is held yieldingly in the direction of the shaft 9 by the Weight 55, which is so adjusted on the bent arm 54 of the lever 52 that the pressure of the middlings will press the disk 33 to the right, to permit the middlings to pass to the discharge 38. The weight 55 may be so adjusted on the bent arm 54 of the lever 52 as to retard the discharge of the middlings as may be desired.

Having thus described our invention, we claim as new and desire to secure by Letters Patent -1.
